INTERGENERATIONAL SUPPORT EXCHANGES AND OLDER PARENTS' CARE RECEIPT AND EXPECTATIONS

Abstract Distinguishing between support and care, this study investigated how different types of past support exchanges with children were associated with older parents’ care receipt and expectations. Older parents (N=190; Mage=79.98) reported on tangible, non-tangible, and childcare support exchanges with each of their adult children (N=709; Mage=52.69) in two waves of the Family Exchanges Study (2008 and 2013). Multilevel, within-family, logistic regression models were estimated. Parents with functional limitations more likely received care from children whom they received more tangible support from at the prior wave. Parents without current limitations more likely named children whom they previously provided childcare support to and received more tangible support from as their expected future caregiver. These findings emphasize continuity in the transition from receiving tangible support to receiving and expecting care from adult children. The importance of older parents’ childcare support given to adult children also highlights reciprocity in intergenerational care exchanges.

that may be exacerbated when parents need increasing support. Evaluations or appraisal of providing support may mediate the links between stress and outcomes. Using structural equation modeling, we assessed the relationship between change in parental disability and intergenerational ambivalence through adults' perceptions of the stress and reward of providing help to parents. Participants included 369 adults (32% Black, 68% White) who provided information on 478 parents from Waves I and II of the Family Exchanges Study. The association between change in parental disability and intergenerational ambivalence was explained through stress appraisal; greater parental disability led to higher stress appraisal which led, in turn, to greater intergenerational ambivalence. The model did not significantly differ by race. Results show that stress, rather than reward, appraisal is an essential factor in determining relationship quality as parental care needs emerge. Very old adults (80+) are the fastest growing population worldwide. Children of the very old adults may see their prolonged relationship with parents as a benefit (e.g., longer time together) but also as burden (e.g., prolonged responsibility in their own late life). Using a sample of older children (N = 219) from the Boston Aging Together Study and Korean Aging Together Study, we investigated the factors associated with older children's (aged 62-76) reports of burden in their relationships with very old parents (aged 81-101), focusing on how family relations were imbedded in different cultural contexts. Overall, American older children showed lower levels of burden, compared to Korean older children. The factors associated with burden differed by country; support given to parents and relationship quality were associated with American older children's burden, whereas support received from parents, familism, and negative relationship quality were associated with Korean older children's burden.

CHRONIC NEGATIVE SOCIAL TIES: IMPLICATIONS FOR EXPOSURE AND REACTIVITY TO DAILY SOCIAL INTERACTIONS
Kira Birditt, Angela Turkelson, Richard Gonzalez, and Toni Antonucci, University of Michigan, Ann Arbor, Michigan, United States Negative relationships (i.e., irritating, demanding) predict poor well-being and daily processes may account for these links. This study examined longitudinal trajectories of negative ties and their links with daily social interactions and well-being. A total of 169 individuals ages 33 to 91 reported negative relationship quality (spouse/child/friend) in 1992, 2005, 2015, and 2018 and completed 4-5 days of surveys every three hours regarding positive and negative social interactions and negative affect. Latent class growth models revealed two trajectories of negative relationships (moderatestable and low-decreasing). Individuals in the moderatestable trajectory reported more frequent daily interpersonal tensions but no link with positive interactions. The link between negative relationship trajectories and daily negative affect was moderated by daily positive interactions such that the association was reduced when individuals had positive interactions. Thus, negative ties may increase exposure but not reactivity to daily tensions and daily positive interactions buffer the negative tie-well-being link. Previous caregiving research has focused on a single care recipient; however, no research has explored the potential simultaneous care needs of fathers and mothers in the same family. Drawing from gender role theory, we use qualitative data from 76 spousal dyads from the Within-Family Differences Study to compare fathers' and mothers' explanations of which adult child they prefer as their future caregiver. In 72% of families, fathers and mothers did not share the same care preferences suggesting that care preferences are dispersed among multiple adult children within the same family. In families in which fathers and mothers shared care preferences, 75% chose the same daughter. Additional findings showed that fathers' explanations for a preferred caregiver aligned with mothers' explanations; however, differences were identified based on children's gender. These findings shed light on the similarities and differences in parental care preferences and underscore the influence of gender in family care networks.

UNDERSTANDING MOBILITY, HEALTH, AND WELL-BEING OF OLDER ADULTS USING SENSING TECHNOLOGIES
Chair: Christina Röcke Co-Chair: Minxia Luo Discussant: Hans-Werner Wahl Mobility has been identified as one important ingredient to older adults' health and well-being and is considered a high priority in the global agenda of healthy and active aging. However, mobility is still a relatively understudied concept in aging research. This symposium, including three empirical studies and one concept paper, presents how different sensing technologies can be utilized to examine mobility, health and well-being in older adults. Using infrared motion sensors and contact sensors, Wu and colleagues examine indoor mobility and show its associations with physical, cognitive, and mental health in community-dwelling older adults living alone. Luo and colleagues use a custom-built mobile GPS sensor and a smartphone-based ambulatory assessment to examine daily mobility and well-being in communitydwelling older adults. They find that a day with larger life space area, more time spent in passive transport modes, and higher number of different locations is associated with higher daily life satisfaction. Similarly, using a GPS sensor combined with a smartphone-based ecological momentary assessment, Kamalyan and colleagues examine life-space mobility, social interactions, and well-being in older adults with and without HIV. They show that prior day's at-home time is negatively associated with current day's happiness and that prior day's social interactions diminishes this association. Jansen presents a project combining sensor-based movement data, GPS-based geolocation data, and experience sampling to investigate relations between life-space mobility and social participation and the role of cultural and climatic differences across several European countries. Hans-Werner Wahl will discuss all papers from an ecological and contextualized aging perspective. Mobility as a multidimensional concept has rarely been examined as a day-to-day varying phenomenon in its withinperson association with older adults' daily well-being. Using a custom-built mobile GPS sensor ("uTrail") combined with a smartphone-based ambulatory assessment, this study examined associations between daily mobility and daily well-being in community-dwelling older adults. Analysis included 947 days' data from 109 Swiss older adults aged 65 to 89 years. Multilevel modelling showed that, within persons, a day with larger life space area, more time spent in passive transport modes, and higher number of different locations
